Synthesis and Luminescence of Eu Complex Incorporated MCM-41 Mesoporous Molecular Sieves
View through CrossRef
Rare earth complex Eu(phen)2Cl3·2H2O synthesized by precipitation method was
incorporated into MCM-41 mesoporous molecular sieves which were synthesized via a
hydrothermal method. Hybrid inorganic/organic mesoporous luminescent material
Eu(phen)2/MCM-41 has been characterized by XRD, TEM, IR, UV-visible spectra and
fluorescence spectra. Results indicated that the hybrid mesoporous material has typical structure of
MCM-41 and retains the same pore structure as MCM-41 after the assembly process. The
fluorescence spectra of these materials present a series of narrow lines assigned to 5D0 → 7F0,1,2,3,4
transitions. The high emission intensity observed is a promising property for application of the rare
earth complex in technological luminescent devices.
